Embodiment 1

[0018] In the present embodiment, citrus and guava are interplanted to control the method of citrus psyllid pest damage, and the steps are as follows:

[0019] 1. Gardening and land preparation: choose to build a garden in a plot with deep soil, convenient transportation, sufficient sunshine, and sufficient water source; before planting, carry out deep plowing, burying weeds, and drying in the sun, turning once every 2 days, and plowing 3 times Finally, according to the cultivation spacing of 2.5X1.5 meters, the planting density is 99 to 100 plants / mu specifications to dig planting holes; apply compound fertilizer at the bottom of the holes.

[0020] Planting of seedlings: Select citrus seedlings and guava seedlings with strong root system and many fibrous roots for planting. Plant a guava after every 5 citrus trees, and so on; in the second row, plant a guava after the fifth citrus tree from the last one, and then plant a guava after every 5 citrus trees Guava, and so on. S...

Embodiment 2

[0025] In the present embodiment, citrus and guava are interplanted to control the method of citrus psyllid pest damage, and the steps are as follows:

[0026] 2. Gardening and land preparation: choose to build a garden in a plot with deep soil, convenient transportation, sufficient sunshine, and sufficient water source; before planting, carry out deep plowing, burying weeds, and drying in the sun, turning once every 2 days, and plowing 3 times Finally, according to the planting spacing of 3.5X2.5 meters planting specifications dig planting hole; bury compound fertilizer at the bottom of the hole.

[0027] Planting of seedlings: select citrus seedlings and guava seedlings with strong root system and many fibrous roots for planting, and at the same time interplant a guava in the first row starting from the first and counting down the 7th citrus tree, and then Plant a guava after every 7 citrus trees, and so on; in the second line, plant a guava after the last 7th citrus tree, a...

Embodiment 3

[0032] In the present embodiment, citrus and guava are interplanted to control the method of citrus psyllid pest damage, and the steps are as follows:

[0033] 3. Gardening and land preparation: choose to build a garden in a plot with deep soil, convenient transportation, sufficient sunshine, and sufficient water; before planting, carry out deep plowing, burying weeds, and drying in the sun, turning once every 2 days, and plowing 3 times Finally, according to the cultivation spacing of 3X2 meters, the planting density is 99 to 100 plants / mu specifications to dig planting holes; apply compound fertilizer at the bottom of the holes.

[0034] 4. Seedling field planting: select the citrus seedlings and guava seedlings with strong root system and many fibrous roots for field planting, and set 5 treatments, which are A (single cropping citrus): only plant citrus; B (citrus row Interplanting guava): planting citrus, and interplanting a guava after the 6th citrus tree in the first row...

Abstract

The invention discloses a method for controlling diaphorina citri insect pests by interplanting citrus with guava, and relates to the technical field of agricultural planting. The method comprises thefollowing steps: citrus are planted by adopting a conventional method, wherein the line spacing of the citrus is 2.5-3.5 meters and the plant distance is 1.5-2.5 meters, so that a citrus garden is formed; guava is interplanted into citrus trees, one guava tree is interplanted every 5-7 citrus trees from the first citrus tree in every uneven row, and one guava tree is interplanted every 5-7 citrustrees from the last citrus tree in every even row; and the guava trees is 80-100 cm higher than the citrus trees through trimming, single rows of guava are planted around a citrus garden, and the plant distance of the guava trees is 1.5-2.5 meters. Citrus diseases and insect pests are prevented and controlled through plant diversity, diaphorina citri in the citrus garden is greatly reduced, costof spraying large amounts of pesticides is reduced, pesticide damage is avoided, infection risk of citrus huanglongbing disease is reduced, and remarkable economic, social and ecological benefits areachieved. Researches show that the control effect of interplanting the citrus with guava reaches 54-90%.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for interplanting citrus and guava to control citrus psyllid pests. Background technique [0002] Citrus huanglongbing is one of the most devastating diseases in citrus production in the world. Once citrus is infected with this disease, there is no rescue measure. Huanglongbing is called "citrus cancer". Citrus trees infected with Huanglongbing can only be dug up to avoid infection. Currently, there is no effective treatment agent and drug delivery method. The initial investment in citrus planting is large, and the infection of Huanglongbing is a devastating blow to fruit farmers. [0003] Huanglongbing does not spread infection through soil, running water, strong wind, pruning, other insects and animals, only psyllids are the main medium of its transmission. The psyllid mainly feeds on the young shoots of citrus, and the summer shoots of citrus suffer th...
